Re: Forms security: Not displaying input means it is protected? --zivi-muh

Ah that would explain it, I did scan your email over 3 times to be sure I wasn't misunderstanding!

I haven't used the security component in this way yet so I am afraid I can't be of any further help

I will use this component soon however, thanks for reminding me of its existence :)

Kind Regards

Thanks for the hint to the $whitelist, Stephen. But this seems not
necessary to me anymore when using the Security component (which I do
and I forgot to mention in my first post). Look at this
(http://book.cakephp.org/view/175/Security-Component):

"When using the Security Component you must use the FormHelper to
create your forms. The Security Component looks for certain indicators
that are created and managed by the FormHelper (especially those
created in create() and end()). Dynamically altering the fields that
are submitted in a POST request (e.g. disabling, deleting or creating
new fields via JavaScript) is likely to trigger a black-holing of the
request. See the $validatePost or $disabledFields configuration
parameters."

So if you're using Security component, the end user can't mess with
the POST data anymore. :-)

Any other comment about this, anyone?
